12th month came on the 29th with menstruation, it has never been on time and with menstruation

Patient's question:

No

Doctor's answer:

Generally speaking, pre-ejaculate may also enter the vagina unintentionally in some cases, and this situation is not ruled out as a possibility for pregnancy.
You have a history of delayed menstruation. It is recommended to take a pregnancy test if your period is delayed by more than three days to rule out the possibility of pregnancy. If pregnancy is ruled out, a delay of one week and an advance of one week in the menstrual cycle are generally considered normal. Please note that this is not a face-to-face consultation and the advice is for reference only.
